Crud Crudcatcher / Raceguard Mud Guard from £11.27 @ Amazon

It was chucking it down when the boys needed to leave for school, which made me think that they need some mudguards for their bikes (their white shirts would no doubt be filthy otherwise).

I've found the Crud twinpac mudguard set from Amazon which looks like a good buy (I've got an older version of these on my MTB). The white version is £11.27 dispatched and sold by bikes4life, while the black version is available directly from Amazon at £12.49. Both prices include delivery.
